ASTM D 3754:2024

1.1 This specification covers machine-made fiberglass pipe, 8 in. (200 mm) through 156 in. (4000 mm), for use in pressure systems for conveying sanitary sewage, storm water, and many industrial wastes, and corrosive fluids. Both glass-fiber-reinforced thermosetting-resin pipe (RTRP) and glass-fiber-reinforced polymer mortar pipe (RPMP) are fiberglass pipes. This standard is suited primarily for pipes to be installed in buried applications, although it is acceptable to be used to the extent applicable for other installations such as, but not limited to, jacking, tunnel lining and slip-lining and rehabilitation of existing pipelines. Pipe covered by this specification is intended to operate at internal gage pressures of 450 psi (3103 kPa) or less. Note 1: For the purposes of this standard, polymer does not include natural polymers. 1.2 The values given in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information purposes only. 3 Grade 1 Polyester resin surface layer- reinforced^B 2 polyester^B resin surface layer- nonreinforced^B 3 polyester^B resin and sand surface layer nonreinforced 4 epoxy resin surface layer- reinforced 5 epoxy resin surface layer- nonreinforced 6 No surface layer 4 Class^C C50 C100 C150 C200 C250 C300 C350 C400 C450 5 Pipe Stiffness psi (kPa) A 9 (62) B 18 (124) C 36 (248) D 72 (496)^ABC 1.3 The following precautionary caveat pertains only to the test method portion, Section 8 , of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Note 2: There is no known ISO equivalent to this standard. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
